On October 31, 2000, Singapore Airlines Flight 006 was preparing for departure from Chiang Kai-shek International Airport (now Taiwan Taoyuan International Airport) to Los Angeles during one of the worst typhoons to hit Taiwan in decades. Typhoon Xangsane was battering the island with winds exceeding 100 mph and torrential rain, creating extremely hazardous flying conditions.
The Boeing 747-412, registration 9V-SPK, was a relatively new aircraft delivered to Singapore Airlines in 1997. Captain Foong Chee Kong, 41, was an experienced pilot with over 12,000 flight hours, accompanied by First Officer Ng Kheng Leng. Despite the severe weather, the crew received clearance for takeoff from Runway 05L.
What followed was a catastrophic case of mistaken runway identity that would become one of Asia's deadliest aviation accidents and expose critical weaknesses in airport safety systems during severe weather operations.
Chiang Kai-shek International Airport had two parallel runways: 05L/23R (active) and 05R/23L (closed for construction). On the night of the accident, Runway 05R was closed due to construction work and was littered with concrete barriers, excavators, and other heavy machinery.
In the severe weather conditions with extremely limited visibility, the crew became disoriented during taxi and unknowingly entered the closed runway. The typhoon's driving rain and wind, combined with poor lighting and inadequate runway markings, created a perfect storm for this tragic error.
The SQ006 accident led to significant improvements in airport safety systems and runway incursion prevention worldwide.
Singapore Airlines Flight 006 serves as a stark reminder of how weather, visibility, and airport infrastructure must work together to ensure safe operations. The accident led to revolutionary improvements in runway safety systems and procedures that protect countless passengers today.
